These yield a ballistic coefficient, which combined with other factors (gravitational force, angle of inclination / declination, air density (temp and humidity), can be used to calculate the flight path of the bullet. But at 1000 m/s (~3281 fps), well in the velocity range of current rifles (a bit faster than most 200 grain / 13 gram bullets), nothing prevents contact with air, so the bullet undergoes matter/anti-matter annihilation on all surfaces. Assume firing from a rail gun. It would never make it out of a barrel pushed by a propellant. | |

It'll travel slightly further than you might think, but not enough to make any practical difference to the shooter. | |
